I used to have a Sunnto Hiking watch, then switched to a Tissot Touch Plus Titanium watch,
The Sunnto was gone due to my mistake in damaging the battery cover latch. Tissot was dead after using for three years and I sent to repair, Now is OK.. My next consideration is this Casio as I have seen a lot of Hikers are using this watch. Besides, I have a LL Bean which I recently used a lot for Hiking! LL bean is in fact Hamilton watch, built with simple solid piece of Steel plated with Chrome, hand wind, sturdy design. It can keep time well under extreme temperature conditions But it is a bit small in size.
The Casio Pro Trek. Triple Sensor, Tough Solar with Titanium strip.
There a few verison of diffferent prie tags, Made in Japan and Thailand have 2X price difference.
Friend of mine told me that there is another version that can have Radar-Satellite detection signal code included. Which mean, if some with loss in the jungle, signal transmission to tell helicopter the position!
Beitling used to have a special for Pilot that has a function of sending RF signal to nearby rescue station for alert. I have seen that, quite expensive!
